R12 installation is one of the crucial task for Apps DBA.Below are the steps described:Preparation for Oracle Apps R12 Installation:
User & Mount point/File system :
We have created two users for installing Oracle R12 Application (one for database tier & another for middle tier also called as application tier). We need 73 GB space (45GB DB & 28GB application tier)
1)Create groups & Users for Oracle R12 Application software installation:
su - root
#groupadd dba => group of users to be granted SYSDBA system privilege
#groupadd oinstall => group owner of Oracle files
#useradd -m -c -g oinstall -G dba oracle =>For Database tier
#useradd -m -c -g oinstall -G dba applmgr =>For Application tier
passwd oracle
passwd applmgr
2) Minimum Requirement for Oracle R12 Application installation:
CPU & RAM
CPU 1.6 GHz
RAM 1GB
Staging Area
We need to use adautostg.pl available in Start Here CD.Advantage of using staging area is that after start CD you don’t have to manually insert CD’s and Installer will automatically pick next CD from staging Area. We can pass on configuration setting on first 3-4 screens & once installer starts we can see complete installation. In case of any failure or subsequent installations (If you have to install more than one Instance its always better to install using Staging Area)
[root@test]# more /etc/hosts
127.0.0.1 localhost.localdomain localhost
Open your hosts file wiht editor(I will use vi editor in this article),put your info in this file and save it. In this article my localhost will be test, my localdomain will be helios.com
PS: If you are using standalone server or pc you can give use any domain name you want. But if your server or pc on any domain you must use localdomain.
[root@test]# vi /etc/hosts
127.0.0.1 localhost.localdomain localhost
10.100.x.x test.helios.com test
2. Set Kernel Parameters:
Add following line in end of the /etc/sysctl.conf file.
[root@test]# vi /etc/ sysctl.conf
#R12.1.1 kernel settings
kernel.shmall = 2097152
kernel.shmmax = 4294967295
kernel.shmmni = 4096
# semaphores: semmsl, semmns, semopm, semmni
kernel.sem = 256 32000 100 142
fs.file-max = 327679
net.ipv4.ip_local_port_range = 10000 65000
net.core.rmem_default=262144
net.core.rmem_max=262144
net.core.wmem_default=262144
net.core.wmem_max=4194304
#full qualified hostname(format is host.localdomain) << optional
kernel.hostname = test.helios .com << optional
#correct domain name !! << optional
kernel.domainname = helios.com << optional
After this steps you must set your new settings wiht below command:
/sbin/sysctl –p
3. Update /var/tmp/.oracle with 777 permissions
chmod 777 /var/tmp/.oracle
4. Edit /etc/security/limits.conf file:
Add the following lines to the /etc/security/limits.conf file:
[root@test]# vi /etc/ security/limits.conf
* hard nofile 65535
* soft nofile 4096
* hard nproc 16384
* soft nproc 2047
5. Edit /etc/resolv.conf file:
Add the following lines to the /etc/resolv.conf file:
options attempts:5
options timeout:15
6. Check /etc/sysconfig/network files format:
Verify that the /etc/sysconfig/network file is formatted as follows:
HOSTNAME=[node_name].[domain_name]
7. If the /etc/sysconfig/networking/profiles/default/network file exists, remove it.
If you changed any files in the previous steps, restart the system.
Be sure we have below rpms on our system:
The following i386 packages must be installed from the OEL 5 or RHEL 5 distribution media:
• compat-glibc-2.3.4-2.26
• gcc-4.1.2-14.el5
• gcc-c++-4.1.2-14.el5
• glibc-2.5-123
• glibc-common-2.5-123
• glibc-devel-2.5-12
• libgcc-4.1.2-14.el53
• libstdc++-devel-4.1.2-14.el5
• libstdc++-4.1.2-14.el53
• make-3.81-1.13
• gdbm-1.8.0-26.2.13
• libXp-1.0.0-8.1.el5
• libaio-0.3.106-3.23
• libgomp-4.1.2-14.el5
• sysstat-7.0.0-3.el5
• compat-libstdc++-296-2.96-138
• compat-libstdc++-33-3.2.3-61
Additionally, the following RPMs are required for an 11gR1 Database (which is bundled with the 12.1.1 release) on the database tier:
• elfutils-libelf-devel-0.125
• elfutils-libelf-devel-static-0.125
• libaio-devel-0.3.106
• unixODBC-2.2.11
• unixODBC-devel-2.2.11
• kernel-headers-2.6
Create folder for Oracle E-Business Suite R12.1.1 installation
Firstly check the mount point size of server.
As we can see i have free space, so i will create my stage folder and my installation folder on this mount point.
[root@test]# cd /data
[root@test data ]#mkdir TESTR12
Here we are doing Fresh Installation .Give 777 to installation folder.
[root@test]# chmod 777 /data/TESTR12
Create related folder for Application and Database tier(optional):
we want to put application tier installation folder together(also database tier installation folder) together we can create 2 subfolders under my main installation folder TESTR12.
[root@test]# cd /data/TESTR12
[root@test TESTR12]# mkdir apps
[root@test TESTR12]#mkdir db
We must give permisson to our user for can make installation of those folder
[root@testR12]# chown –R appltest:dba /data/TESTR12/apps
[root@testR12]# chown –R oratest:dba /data/TESTR12/db
C. Installation wizard steps:
D. After Installing of R12 Application:
Perform the following steps after installing or upgrading to Release 12.1.1 and before allowing users to access the system.
Relink Advanced Supply Chain Planning executables (for SLES 10 and OEL/RHEL 5.4 or higher only)
During the relink phase of the installation of EBS Release 12 (12.1.1) on OEL/RHEL 5.4 (failures will result while relinking the Advanced Supply Chain Planning (ASCP) executables. To fix this problem, users are required to replace the following line under the Linux section of the $AD_TOP/bin/adrelinknew.sh:
CPP_LDFLAGS=' -L$(ORACLE_HOME)/lib -L$(ORACLE_HOME)/lib/stubs -lclntsh'
with
CPP_LDFLAGS=' -L$(ORACLE_HOME)/lib -L$(ORACLE_HOME)/lib/stubs -lclntsh -Wl,--noinhibit-exec'
After making this change, users are then required to run the adadmin utility and relink application executables.
